d² = 20² + 20² ← Pythagoras' identity
= 400 + 400 = 800 ( take the square root of both sides )
d = ≈ 28.28 ( to 2 dec. places )
Answer:
diameter ≈ 11 feet
Step-by-step explanation:
The area (A) of a circle is calculated using the formula
A = πr² ← r is the radius
To find r divide both sides of the equation by π
r² = =
Take the square root of both sides
r = ≈ 5.5 feet
Diameter = 2r = 2 × 5.5 = 11 feet
